Economical CO2 adsorbents are gaining significant attention as viable solutions to combat climate change. This research assessed the adsorption potential of solid residues following gasification bagasse (SR-Bagasse), bamboo (SR-Bamboo), and rice husk (SR-Rice husk) in various systems Vietnam Cambodia. Among these residues, SR-Bagasse showed highest capacity, followed by SR-Bamboo, while SR-Rice exhibited moderate performance. The capacity at 25 °C with 100 % flow varied from 6 9.5 adsorbent's weight. Under flue gas conditions (15 85 N2), ranged 2 5 %. Additionally, chars demonstrated recyclability 90 initial retained after 30 cycles, making them comparable several advanced studied previously. performance could be attributed its substantial microporous ultra-microporous volumes, micropores serving both sites conduits ultra-micropores. study's findings emphasize for integrating energy production development economical scalable industrial use.
